Entertaining action game.
Some things you could include if you decide to do a sequel. Weapon upgrades or Finding weapons - Pretty self explainitory things such as a new sword or a bow, something to change it up.
Horse riding! - Those running scenes could have definitely used a mount because really a Knight is almost commonly known for the steeds that they ride into battle.
Shields - Great idea for both the hero and the enemies but you shouldn't be able to run through a shielded down enemy and continue attacking him.
Lock down - Not fun getting locked down in fire from a bow and axe goblin while a mace orc is constantly swinging away protecting them.
Useless coding - From what I played the jump command was useless and actually made you die more often than using your shield.
Somethings I did enjoy were the music, the background made the forest seem more alive, the personality of the character (Promising the orc he'd let him live then killing him made him seem like more of a realistic brooding hero.)
Overall good job.
